Twenty Ten[resolved] How to exclude pages from the black subheader (4 posts)

I am using the 2010 theme for my site which uses mainly Pages. Well, since I am writing a lot of pages, the Subheader keeps on showing more and more pages as time goes on, and it's looking ugly now.

Is there a way, or a plugin that can exclude Pages from showing in the black subheader? I want the pages to show up in the sidebar navigation, but I'd only want the most important pages to show in the Subheader.
